Proper Divine Office Chants of the Ecclesiastical Province of Prague

The main goal of this project is to collect chant tunes necessary for celebration of the Divine Office on feasts proper to the ecclesiastical province of Prague (historical territory of the kingdom of Bohemia, western part of today's Czech Republic) according to the calendar and liturgical texts in place right before the liturgical reform of the Second Vatican Council. As an extension of that primary goal, tunes should subsequently be edited also for Latin texts of the post-Vatican II LOTH proper of Czech Republic, which share a significant portion of chants with the older provincial proper.

Additional information in Czech:

While most of the liturgical texts and chants are of little liturgical use beyond the borders of Bohemia, the formulary of St. John Nepomuk (S. Ioannes Nepomucenus, Hl. Johannes von Nepomuk) was indulted to many dioceses throughout Germany and elsewhere. Our list of discovered chant sources for the feast covers several independent regional traditions/authors and may be of broader international interest.
